SEAT DESK.

Application tiled February 28, 1921. Serial No. 448,150.

To all 107mm t may conce/Mt.'

Be it known that I, CriRisToPHER VINKEL, a citizen of the United4 States, residingat Cleveland, in the county of Cuyahoga and f State of Ohio, have invented a certain new and useful Improvement in Seat Desks, of which the following is a full, clear, and exact description.

One object of the invention Vis to provide l" simple,V durable and easily manipulated mechanism for so supporting a desk or table that it may be moved in various vdirections and into many positions'by and lfor the 'convenience of different users,'and wit-hout dany 5 ger that any part of the person sitting in a .chair behind the tablewill be pinched or bruised, when the table is moved to or from the various positions it may occupy.` Another object is to prevent the easy displace-- ment of the table, through accident or mischievous intention either from the substantially horizontal operative position, lor the turned up out-of-'the-wayv position.

The invention consists in the construction and combination of parts shown in the drawing as herein described and definitely point- .ed out in the appended claims. f

'ln the drawings, Fig. 1 is a side elevation lof a desk chair which embodies the invention, viewed from the vleft side thereof; Fig.

'2 is a planview thereof; Fig. 3 is a side elefv vation fromA the'r right side of said deskchair. Fig. 4 isay front elevation ofsaid desk-chair with some of the parts broken the foregoing figures shown the desk-chair when the table is in operative or usable poscapable of being moved to and held inva-` riouspositions.

The chair represented/.by 10 maybe of any suitable construction. The desk or table 15 is adjustably supported, through mecha` away, and shown in vertical section. All of upon a standard, so thatsaid table Ashall be.

nism in which the present invention is einbodied, ona vertical standard 21 ywhich secured to the chair at the front right hand corner thereof,-said standard being located in advance of the chair seat 14, and having its lower end extend downto engage `the floor, and thereby serve as the right hand front leg 12 -of the chair. member is mounted to slide vertically on this standard and may be-'seoured thereto at any desired elevation. l comprises a metal plate 22,'w'hch isplaced This extension 'member An extension against the outer, il e., right hand, faceof the standard, and is provided with flanges 23 which engage with the front and rear edges of said standard; and a clampingI plate 24 which is placed in Contact with vthe innerface of the standard. Bolts 25 which pass through vertical slots 21a in the standard 21, and hand nuts26A thereon aiford/ means for securing the extension at any` de sii-ed elevation to the standard-by. drawing i the plates 22, 24, toward one another and thereby clamping the standard `between them.

rlhe mechanism forsupportingthextable j'.

or desk 15 is carried by the extension mem- 2ber and goes np and down with it.,A ,The

mechanism by which the table issupported permits it to be moved horizontally forward and backward, and to be tilted about a horizontal axis whichextends transversely, and

also to be swung about a'.v horizontal airisy which is at right angles to the. tilting laxis whereby it may. be in operative positionin .front of the chair or may be swung upto a substantially vertical position out` ofjthe, Il

way of a pei'son who out vot the chair.

Thel speciiic `mechanism shown Vin -theA desires to sit` in or get l 1 drawing for endowing the table'withthe` capacity to move as stated is Vas follows: The upperends ofthe two flanges 23e-tre slightly prolonged upwardand serve as earsl A horizontal shaft 28 isA mountedin these ears and extends between them, andy i-s prolonged in front of the front ear.r Snitable means are preferablyl provided for preventing the shaft from moving endwise in.

these ears... This result may. be attainedby driving the s haftrtightly into the holesl'i-Ii thel ears; or it may bev vproduced by any otlien I suitable means. A sleeve34fis1'ixed'toone end of ay bracket 30 and embraces and lis s'idable uponv this rock 'shaft betweentlie 'Alloy two ears 27 and the bracket extends from said sleeve transversely in iront of the chair. The table or desk 2O is secured to this bracket by means which will be presently described. But it is obvious that by the turning oi" the sleeve 34 upon shat't 28 'the table may be made to occupy eithei` of the positions in which it is shown in the drawing.

While the construction shown is, as has Vbeen described, such that the sleeve 34 turns upon and slides along the shait/S, it is of course obvious that the essential thingis thatthe table shall be capable of moving lengthwise of the shaft and of swinging about the axis of the shaft. `The specific Construction as described is preferred not because it has any functional advantages over other constructions by which the stated movements could be secured,v but because it isr somewhat cheaper than any other construction T have thought of.

The bracket 30 is in the form ot a hollow cylinder, and it is provided with a rigid dependingarm 32 near its supported end in such position that kwhen the cylindrical portion occupies a substantially horizontal position, the depending bracket arm 3&2 will engage the clamping plate 24 and thereby support the bracket in the stated position,l as best shown in Fig. 4. This bracket 30 is ormedwith two ears 33 on vone end which ears tightly embrace the sleeve 34, andconsequently embrace the shaft 28. The sleeve 34, as stated, liesbetween the ears 27, although the length of the sleeve is substantially less than the distance between the ears 27, so that s aid sleeve may move several lio inches forward and backward upon the shaft, said movement being limited by the engagement of the sleeve with one or the other of the ears 27.

Tnthe construction shown the arm ot' the bracket SOris made of pressed metal, bent il'itoU-shape, and 'formed with two arms 3Qn which lie against the sides ot the cylindrical part of the bracket, and are welded or otherwise secured rigidly thereto. And this bent metal piece may be formed withY ears 32", which also tightly embrace the sleeve 34. and thereby reinforce and strengthen the connection between it and the bracket,

The table or desk Q0 is associated with two bars 40 `which eXtend forward and backward and are secured to its under side at a proper distance apart. A short cylinder or disk 88 is rotatably mounted in each end of' the cylindrical portion of the bracket 30. Each ot' these disks38 is provided with an upwardly extendedarm 39 which is rigidly fixed to ,the adjacent bar LQ-said arms 89 passing through arcuate vnotches 30d inthe lends ot the cylindrical vfp'art of the bracket. One ot these disks 38, at least, carries bolt 41 which passes through a circumferential slot 3T in the cylindrical wall of bracket 30, and it has a thumb nut 42 on its outer end which when screwed up will clamp the disk 38 iinmovably in the cylinder.

The desk may be moved ward or away from the occupant of the chair by causing the sleeve 34 to slide on shaft Q8. Likewise the desk may be tilted to a considerable extent, which movement is permitted by the turning of the disks 38 in they ends of the cylindrical part oli' the bracket. When it is tilted to the position desired it will be clamped in that position kby 4turning up the thumb nut 42.. l

l/Vhen the desk is not in use it can be turned about the axis of shaft 28. and swung into the substantially vertical position shown in Fig. 4. There will then be nothing in front of the chair, and 4there'lore a person may get to and from the chair as easily as if there were no desk attachment thereto. Vhen, however, it is desired to use the desk it is turned down to the vposition shown in Fig. 4, at which time the arm 32 of the bracketengages the clamping plate 24 and holds the desk in substantially the position shown.

Tt is desirable that when' the table is in a horizontal position, a mischievous scholarl in the associated chair shall not be able to easily vibrate the table up and down and position and cause arm 32 to bang against the clamping plate. l

Both of these results are attained by means of a spring clamfping plate whichl along its loweredgeisy Xed to the standard extension 22, and has a bead 56 alongits upper edge, ttor engagement in lone or the other`- of the notches 30c or Bof in the peripheries of the ears which embracey vthe sleeve 34.

horizontally to hun This spring plate 55 will yield if a sufficient torce is applied to the table to turnit aboutthe axis of shaft 28, but it will prevent a slight push whether accidental or intentional on the table whenin thc position shown in Fig. 5, from starting to swingr downward; and it will prevent one 'Eromvibrating the table up and down when it 'clothes caught between theend of arm 32.-

and theplatef24; and it performs this func-- tion because it always hangs down in contact with plate 24 regardless of the position of the table. This shield also hides from view" j an inkwell 5l issupported beneathY a `pen hole. 17 in the table top,-through which hole appen maybe passed to the inkwell. rl`he inkwell holder is slidably supported `uponv shaft 28, but in such wise that the ink l -well holder may not turn on the shaft.

As shown the inkwell holder includes va bar 52 which yextends over and is in substan# tial contact with the front ear 27, and' has' two downwardly extended ears 53 which loosely embrace shaft 28, oneof them also embracing sleeve 34.; Therear ear 53 projects between the front earta of the shield 45, and a collar 34e on the sleeve 341C. This v compels the inkwell holder to move forward and backward with the table, and thereby shaft 28.

always preserves the necessary relation with the hole in the table top, but the engagement of theinkwell holder top bar 52 with the top of the front ear 27 prevents the inkwell holderl from turning about the axis of Having' claim l.- In an adjustable table, the combination of a standarda horizontal shaft-mounted on the upper end of said standard, a bracket supported at one end byl said shaft and prodescribed myinvention, I
